[companion question here]
I was given an 11x11x11 Rubik's cube as a gift. It came with a guide book that I have been following to solve the cube.
I have solved four of the 9x9 sub-centers of the cube, and arrived at the step to solve the 5x5 sub-sub-centers of the remaining two. There is an error in the guide book notation, where it has duplicate algorithms (circled in red) to swap two different pairs of pieces:
The top right algorithm is correct -- it swaps the rightmost center piece of the 5x5 sub-centers. However, the bottom left algorithm is incorrect; it does the same thing as the aforementioned one. What is the correct algorithm to do here?
